National Snow and Ice Data Center

The National Snow and Ice Data Center (NSIDC) studies our world's frozen realms, or cryosphere. We specialize in snow, ice, glaciers, frozen ground, and climate. We also manage and distribute scientific data on the cryosphere, and support other researchers who use the data. We share our data and knowledge with the public.

NSIDC is part of the University of Colorado’s Cooperative Institute for Research in Environmental Sciences.

If you have a question about sea ice or climate, visit our Icelights page at: http://nsidc.org/icelights/
